i5 3570's multiplier is set to 42 and remains limited to 4GHz
Hi, everyone! I'm struggling to push my CPU overclock. I've adjusted the core multiplier in BIOS to 42, but testing and games still cap it at 4 GHz instead of the desired 4.2 GHz. Also, I can't increase the ratio multiplier beyond 42—it just restarts automatically. I tried removing the CMOS battery, but it didn't work. The BIOS version I'm using is the latest one on the Asus site, 1402.
Specs:
CPU: i5 3570 3.4 GHz with Zalman air cooler
MB: Asus p8z77-v lk
RAM: 16 GB 1600 MHz
VC: GTX 1060 3 GB
You're wrong about the situation. Your CPU is an i5 3570 and it isn't unlocked because, as you can see in your photo, it doesn't have a 'K' at the end. Processors with a 'k' are unlocked and allow higher OC. Also, each processor has its own limit, so someone else with the same CPU could achieve a different OC.
You need to reconsider. Your CPU is an i5 3570 and it isn't unlocked because, as you can see in your photo, it doesn't have a 'K' symbol next to it. CPUs with a 'K' at the end are unlocked and allow higher OC. Each processor has its own limit, so someone with the same CPU could achieve different OC levels. I guess you're right, but I still think I can hit 4.2. People say non-K CPUs can still boost the ratio to four steps, which matches what they say, though the frequency is capped at four (with occasional rises to 4.1 or 4.2).
It varies based on the motherboard and BIOS version. Some systems don't permit even a minor adjustment, only turbo. Turn off power-saving features in the BIOS, as they may cause issues. Activate performance mode via the control panel. If possible, set BCLK to 100 manually to prevent fluctuations.

Depends on the motherboard and BIOS version. Some don't permit even a single step increase, just turbo. Turn off power saving from BIOS, as it can sometimes cause issues. Use performance mode via the control panel. If possible, manually set BCLK to 100 to avoid fluctuations. The goal is that BIOS lets me raise the multiplier to 42 (as shown in the screenshot), so I should see a frequency of 4.2. I'll verify the BIOS settings you mentioned, but it's likely they are already correct.

Two points to consider:
1. Is the BIOS maintaining 42 or does it revert to 40 automatically?
2. Some users reported success by updating the BIOS via reflash.

It appears the system stays at 42, but I'll verify later after work. CPU-Z indicates the maximum multiplier available is 42, so it should remain at that level.
Additionally, I've checked if the battery was reset and the BIOS version is up to date (1402), though I haven't performed a reflash yet.
